shm config variables?

I have altered the way I use the config file type of idiom. I have a database table that has the following column id var val description scope The scopes I'm using are template, script, both. I then have a class that loads the variable with template or both into a shared memory segment. Then, these variables are all assigned to the template. This makes them available to every template. The ones with script (and both) scope are treated similarly and loaded into a $_SCRIPT[] associative array. Why do I do this? It allows me to have a simple admin page that controls each of these values. They are stored in the database (I have no interest in maintaining a file), yet the database is only queried on server reboot or on change to the values. Is anyone interested in this? I'm not sure if it qualifies as a plugin perse. But I find it very useful because I dont have the expense of the db queries, yet get the convenience of the values being stored in the db. Steve
